I'm seeing a lot of AI coding ship-fast-now-and-ask-questions-later-tokens-go-burr thinking that leads to things like this github.com/anthropics/c... Sometimes the friction of not being able to magic code into existence is a Feature

[BUG] **EXTREME DANGER**: AskUserQuestion: "No response after 60s — continued without an answer" · Issue #73125 · anthropics/claude-code github.com
AI Weekly's analysis
  • In Claude Code 2.1.198, AskUserQuestion auto-returned a 'No response after 60s' message and told Claude to proceed on its own judgment.
  • The behavior was undocumented, missing from the changelog, and a regression from 2.1.196, which worked correctly per the report.
  • Maintainer ThariqS said a release will expose the setting under /config with the timeout configurable and defaulting to off.

That’s a really good pelican! static.simonwillison.net/static/2026/...

GPT-6 and GPT-5.6 SVG reasoning-effort comparison static.simonwillison.net
AI Weekly's analysis
  • Simon Willison ran his pelican-on-a-bicycle SVG test on GPT-6 Astra alongside GPT-5.6 Sol, Terra and Luna at reasoning-effort levels from low up to max.
  • At max effort, one Astra pelican render used 12,638 output tokens for 63.21 cents; the same prompt on GPT-5.6 Luna cost 1.57 cents.
  • Listed per-million-token prices sit next to the grid: Astra $10/$50, Sol $4/$20, Terra $2/$12, Luna $0.20/$1.20, with xhigh roughly halving both tokens and cost.

I can start to see how "getting enough compute to run the system you're developing with fast enough feedback loops" could quickly become the bottleneck openai.com/index/previe...

1. I had no idea we were building this 2. ... that works!? blog.cloudflare.com/kitesurf/

Introducing Kitesurf: The agent-first browser that runs in V8 isolates on Cloudflare Workers blog.cloudflare.com
AI Weekly's analysis
  • Kitesurf runs entirely on Cloudflare Workers using V8 isolates, built specifically for AI agents rather than human users.
  • Against Chromium it uses 3.1x less CPU and 4.7x less memory on screenshots, but wall time is 1.7-1.8x slower.
  • Existing Puppeteer, Playwright, chrome-remote-interface and MCP/CDP clients work unchanged, and it is free during beta.

Once I learned about the idea of giving an agent a computer vs running an agent on the computer, I haven't been able to unsee it blog.cloudflare.com/cloudflare-c...

Your agent needs a computer, not a container — introducing @cloudflare/computer blog.cloudflare.com
AI Weekly's analysis
  • Cloudflare released @cloudflare/computer, an open-source npm package that orchestrates agent work between lightweight isolates and full Linux containers.
  • The runtime centers on a workspace: a virtual filesystem backed by SQLite that can be populated from cloud storage or source control.
  • Cloudflare's stated goal is a runtime where a container is required for less than 10% of an agent's work.

Recent commentary

A big AI objection around coding has been "If it increases productivity so much, where's all the new software!?" While I'm not sure it's filtered down into consumer-facing stuff quite yet, I feel just inundated with new, ambitious software on a daily basis these days

If you are needing to expose functionality to a sandbox (container, vm, whatever), asking the LLM to "think through this from an OCaps perspective" generates *much* better designs that you might get generally

I don't really think of myself as pro-AI, even as I find myself using it more and more. There are really legitimate concerns about how all of this is going to play out societally! But the Anti-AI crowd seems to have hermetically sealed itself off from new information

One irritation I have with LLMs is that they continually refer to previous revisions of the doc that I am currently having them write "Several conclusions in the first draft were wrong; corrections are called out below." Claude, no one read that. It doesn't exist any more...

I know this can change overnight, but damn. Anthropic seems to have really lost the plot on cost. I bet that as long as their brand holds out this is printing money for them on enterprise deals, but it can't hold forever with such low switching costs

Pondering the commonalities between 3d printing and AI coding - people kinda go a little nuts / obsessive when they first get into it - at first they use it pretty much solely to make accessories for the hobby, or silly toys - output can be useful, but may not stand up to real world use

Seeing LLMs run at 500+ tok/s feels like it breaks something in my brain. Seeing it run at a speed where I can read along makes it feel like thinking has a ~human-level speed. Fast! But still intelligible. Once it gets fast enough it just shatters that illusion. Computer go BRRRRR

Thinking through the work that I'm currently doing at my job, and I honestly think I would not have been capable of doing this work a few months ago without today's frontier LLMs That's pretty neat

Trying to vibe code an idea w/ Fable using the credits Anthropic gave a while back and holy guacamole do those $ numbers just keep ticking up I cannot imagine giving this to employees as an option in a dropdown and then paying API rates 😬
